As promised, Jolla has shown off its newly launched Sailfish OS today, and said that UI will be all about speed and multitasking, while also cutting down on the finger dancing required to use it. The experience will start from the homescreen, where users will be able to control music playback or end a call, for instance, without needing to open the respective apps, using a "pulley" menu system. The Finnish startup also said that "many" Android apps would run on Jolly handsets without modification, though tweaks would be required to get the best out of the system. Jolla foresees the software running not only smartphones from players like new partner ST-Ericsson, but also on tablets, smart TVs and in-car systems, for instance. To see it for yourself, feel free to grab the video after the break.
